See How You Can Play Doom Inside Doom

Do you love the classic shooter Doom so much that you want to play it in the game itself? Like within the actual game?

That's exactly what YouTuber TheZombieKiller did, modding the GZDoom port of the game (via GameSpot) so that you can play the entire, full version of Doom within a small arcade machine in the game. It's a bizarre port to be sure, but it's just the latest in a series of ports including Doom running on an ATM machine and even an inkjet printer. The group has even gotten the in-game Doom arcade machine to play Wolfenstein 3D!

But it's no surprise to shower this much attention on Doom. Upon its release, worlds were shaken. It was another hefty dose of the demon slaying that FPS junkies had come to regard as the pinnacle of PC entertainment. It’s true — they just don’t make ‘em like they used to. Fortunately, with the release of the seminal shooter on Steam, we can indulge in an engaging stroll down memory lane swarming with imps and cacodemons.

Doom is a hardcore traditional shooter. The rules are simple: If it moves, pump it full of lead. As far as the storyline? Not that it really matters in these types of classic fragfests, but you’re reprising the role of a marine who’s descended into the fiery depths of Hell in order to decimate the demons who would exterminate all humanity.

Sure, you may not be able to jump or peer up or down, but your space marine is surprisingly nimble. Puzzles are easily solved and enemies are quickly felled via pure firepower or clever switch-pulling. You can switch between several different weapons: shotguns, pistols, the BFG or whatever strikes your fancy -- there are plenty of tools available to mow down the unlucky demons who cross your path, It’s unabashed, high-octane fragging, with the same WASD and mouse controls you’re likely used to from youth. And it feels just as good as it did then, if not better.

Doom may have been years ago, but it’s still an extremely slick and polished shooter that could easily go toe-to-toe with the twitchfests we’re enjoying now. So if you're reading about this bizarre little mod and feel interested in giving it a try, grab it from Steam or any way that you can so you can see what the fuss is all about. It’s a steal now and a fantastic throwback to the heyday of PC gaming. People are trying to get the title to run on as many systems as possible for a reason, you know.
